commit 1e9f50c73638171403b71d742321464dcd5ef7ed Author: Luis Tomas Bolivar <[email protected]> Date: Fri Sep 8 10:40:32 2023 +0200 Add support for FDB aging In [1] we added support for FDB learning. In order to avoid issues due to that table increasing without limits, which will impact OVN performance, this patch is adding support for its aging mechanisms which was added in OVN 23.09 in [2]. By default is disabled, so if `localnet_learn_fdb` is enabled, the new configuration parameters should be appropriately configured too: `fdb_age_threshold` and `fdb_removal_limit` [1] https://review.opendev.org/c/openstack/neutron/+/877675 [2] https://github.com/ovn-org/ovn/commit/ae9a5488824c49e25215b02e7e81a62eb4d0bd53 Closes-Bug: 2035325 Change-Id: Ifdfaec35cc6b52040487a2b5ee08aba9282fc68b ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!

New options are added to OVN [2] to tackle this problem, and neutron should make use of it [1] https://review.opendev.org/c/openstack/neutron/+/877675 [2] https://github.com/ovn-org/ovn/commit/ae9a5488824c49e25215b02e7e81a62eb4d0bd53 To manage notifications about this bug go to: https://bugs.launchpad.net/neutron/+bug/2035325/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
